Scientific Questions and Detection Methods of Water Ice at the Lunar South Pole
Online published: 2025-07-18
The exploration and study of water ice in the lunar polar regions are of great significance for understanding the origin and evolution of water and volatiles on the Moon, as well as for realizing in situ resource utilization for space exploration. In recent years, the detection of water ice in these regions has become a strategic priority in the competition among major countries, including the United States, China, and Russia, in the fields of lunar and deep space exploration. One of the primary scientific tasks for the Chang'E-7 (CE-7) lunar exploration mission is to detect and investigate water ice at the lunar south pole. In this work, the progress in the exploration and study of water ice in the lunar polar regions is summarized. The unresolved key scientific questions related to polar water ice are presented. Furthermore, the basic information and especially the scientific objectives about water ice detection of CE-7 mission are introduced. The remote sensing and in situ detection methods of water ice at the south pole are discussed based on the scientific payloads onboard the orbiter, rover, and mini-flying probe in the CE-7 mission.
